WRONG!
Where are you going to put the cabinet? It won't fit inside. If you strap it to the roof: first - the doors won't open, second - the cabinet will be on the outside of the stainless steel shell and will dissolve during the time travel transfer.
The only way that this would be remotely possible would be to construct a stainless steel trailer that attaches to the DeLorean, and even then....I'm not 100% sure (I only had one Physics class in High School)
